from May to June is 29%
Step-by-step explanation:
24.
April 30 hr * 6.5 = 195
May 35 * 6.50 = 227.50
percent increase = (new-original)/original
(227.5 - 195)/195
= 32.50/195
.166666
to change from decimal to percent , multiply by 100
= 16.67%
round to the nearest whole percent
=17%
b) May 35 * 6.50 = 227.50
June 45* 6.50 = 292.50
percent increase = (new-original)/original
= (292.50-227.50)/227.50
= 65/227.50
=.285714
to change from decimal to percent , multiply by 100
28.57 %
round to the nearest whole percent
29%
